Brewery Tasting Room in Denver-Boulder

Castle Rock's Small Batch Craft Brewery

We're a nano-brewery featuring a large variety of ales and lagers. We have sixteen rotating taps and we're not tied to any style, so we'll have more than a few beers to crave and we'll always have new beers on hand. Our beers are made by several brewers and all of our staff helps in the brewing process. We are also a gratuity free brewery, so all of our tips go to charity.

Stop into our warm tasting room to enjoy our hand crafted woodwork, made from locally harvested beetle kill pine and used barrel staves, or step outside to enjoy our beautiful patio.
